Authenticity identification of mobile phone. There is no problem with the mobile phone serial number access license. I checked the scrambling code and said my logo was fake. I still moved my heart. Is there a fake in my mind? It's hard to tell the authenticity of a mobile phone by looking at serial numbers and the like now. Since you have the invoice and three guarantees, go to the place where you sell it and find him! The maintenance center said it was a lie, but nine times out of ten it was not. From the appearance, the refurbished machine is easy to lose paint, and it is basically allowed to lose paint within one month. In addition, the refurbished shell feels different from the real machine, and it feels rough when you look at it. Either the keyboard or the crack in the shell will take a few days to reveal its original shape. Or the cell phone signal is weak and intermittent; The battery doesn't work. If all these things are all right in the end, look at the board inside. You fixed it, too I don't know if there is a warranty label on your board, that is, the kind with a date and a gap, which is easy to break. I've met two refurbished machines, that's all.
